当前使用版本(必须填写清楚，否则不予处理)
mybatis-plus-boot-starter： 3.0.7
mybatis-plus-generator：3.3.0
spring-boot-starter-parent：2.0.1.RELEASE
Oracle：11g
该问题是怎么引起的？(最新版上已修复的会直接close掉)
之前用的mybatis-plus-boot-starter-3.0.1版本，没有出现过这个问题，后来升级为了3.0.7，根据文档，要单独引入generator依赖。引入后，某次执行带有查询条件的查询，查出来的结果集理应是空集，但程序却报错了。执行返回值不为空的查询时，可以正常返回。
重现步骤
- 引入generator依赖。
- 执行带有查询条件的查询。且数据库里没有符合该条件的数据。
- 程序报错。
- 更换查询条件的值，使数据库里有符合查询条件的结果，执行查询后能正常返回结果。
- 去掉generator依赖，仅使用mybatis-plus-boot-starter，再执行上述2,4步，无论结果是否为空集，都能正常的返回。
不清楚是否是因为generator里的相关依赖是否与mybatis-plus本身的依赖有什么冲突导致的这个问题。
